Ah, I see... at least I'm pretty sure I do--let me confirm:
So I'm back to a week or 10 days ago (by booting off my SD! external FW drive clone--which I SD! copy back over to a new internal drive when I have it installed), then those--a week or 10 days--old files I now need in order to continue working can be restored to the state of the latest restore that I've done from TCapsule-TMachine (presumably to a state w/in about an hour of when I lost my main internal HD)... for those files that I *notice* I need to get the latest of, when I get back to work.
Then I keep working on my ('new', meaning TC-TM restored) files from then on. If I discover any others that are 'old' I just restore their latest from TC as I discover them (even months later)--which brings them back up to the state they were in (w/in an hour or so of) when my original main internal HD crashed.
So weekly I continue to backup this "new" drive to SD! and if it happens again (my main HD crashes), again I boot from my SD! external drive, restore the files I need from TC and continue working.
It still makes sense to make regular SD! backups whenever one's connected to the FW external drive... but let TC make wireless backups hourly in the meanwhile.
And TC never gets confused, and neither does SD! ... is that correct? And (unlike if I just owned TC-TM alone) I never have to worry about work interruption or time loss due to a down HD, I just boot up from the external SD! FW drive and keep working (and get my crashed internal drive replaced asap of course and re-SD!'ed back over). And I keep all of my hourly file snapshot histories (pre-crashes and post-) on my TC, right?
Works whether you do SD! backups nightly or weekly...
Thanks for listening to me clarify my understanding. (And please correct me if I'm wrong on any of this.)
Cheers,
Brad
PS Main reason I really want TC-TM is because it's hard to get hold of my wife's Macbook long enough to do a "proper" SD! backup more than once a week or so, but she's on our wireless network at home lots throughout the week! :-)
On that note--you have any opinion on the much discussed TC vs. Airport Extreme with an external USB HD connected to it debate (iow, can Time Machine work fine on the latter, rather than paying for the pricey HD in TC)? From what I've read, it seems it's not safe to use the AE + ext. HD, however TC is safe(r). Has that changed and it's now safe to use AE+HD?
